1. In combination, a burner top, a cover for said burner top hinged at its rear edge for vertical swinging movement, an arm rigid with and from said cover at an angle to the assume a substantially vertical when the cover is lowered substantially horizontal forwardly p iecting position engaging the under side of said burner top to limit the upward swinging movement of the cover when the latter is raised, a bell crank lever pivoted directly beneath the burner top and having upwardly diverging for ward and rear arms, the rear arm of crank lever extending in the path of said. firstnamed arm for actuation by the latter when the cover. is'lowered, and means to connect the forward arm of said bell crank lever to an element to be actuated.

2. In combination, a burner top, a cover for said burner top hinged at tical swinging movement, an arm rigid with and projecting from said cover at an angle to the latter so as to assume a substantially depending position when the cover is lowered and 'a substantially horizontal forwardly proiecting position engaging the under side of said burner top to limit the upward swinging movement of the cover when the latter is crank lever pivoted directly beneath the burner top and having upwardly diverging forward and rear arms, the rear arm of said bell crank lever extending in the path of said firstnamed arm for actuation by the latter when the cover is lowered, means to connect the forward arm of said bell crank lever to an element to said bell crank lever in a engagement of lever with said first-named arm and to counterbalance the cover when the latter. is raised.

3. In combination, a burner top, a cover. for said burner top hinged at its rear edge for vertical swinging movement, an arm rigid with and projecting from said cover at an angle to the assume a substantially vertical dependingposition when the cover is lowered and a substantially horizontal forwardly projecting position engaging the under side of said burner limit the upward swinging movement of the cover lever pivoted directly beneath the burner-top .and having upwardly'diverging forward and rear arms, the rear arm of said bell crank lever expath of said first-named arm for cover is lowthe cover is lowered.
